April Ross and Stanford grad Kerri Walsh Jennings pulled into the lead of their pool with their second victory of the 2016 Olympics, a 21-16, 21-9 win against China's Fan Wang and Yuan Yue on Monday.
Jake Gibb and Casey Patterson are 1-1 at the 2016 Olympics following a 21-18, 21-18 loss to Austria.
Ross and Walsh Jennings recorded their 147th team victory in their second-consecutive midnight match of the 2016 Olympics. The pair topped Wang and Yue, 21-16, 21-9, in 35 minutes.
"Tonight was a great night," said Walsh Jennings. "It's such a fun atmosphere. I really enjoy being here. When I wake up at 9, I'm kind of like, 'oh my god, it's ninety more hours to go,' but every hour serves a purpose. The roller coaster; it's such a relief when we get out there."
In the match, Wang and Yue led, 8-7, in the first set before the Americans put together an 8-3 string to take control of the opening set at 15-11. China had eight errors to USA's one.
In the second set, Ross and Walsh Jennings broke from a 5-5 tie with a 16-4 run to end the match.
"Ever since we've been here, we've been staying up late, getting up late," Ross said. "It's not that far off California time, so before I came here I just had in my head that I'm not going to try and adjust to the time change at all."
To clinch their group and advance to the elimination rounds as the third-seeded team, the Americans must defeat Isabelle Forrer and Anouk Verge-Depre of Switzerland on Wednesday or end up with a better point ratio than any team tying them in Pool C.
Ross and Walsh Jennings have outscored their first two opponents by 32 points while the Swiss are a plus-3 and the Chinese a minus-5.
Ross and Walsh Jennings have won all three international meetings with Forrer and Verge-Depre, who defeated Mariafe Artacho and Nicole Laird of Australia, 19-21, 21-16, 21-19, Monday in 62 minutes.
